本文介绍了如何添加TextView的和使用的EditText默认AlertDialog编程的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我一直想在默认AlertDialog添加两个元素，但我似乎无法使它工作。这里是我的code：
//启动对话框
AlertDialog.Builder alertDialogBuilder =新AlertDialog.Builder（本）; TextView的电视=新的TextView（本）;
tv.setText（职称）;
tv.setPadding（40，40，40，40）;
tv.setGravity（Gravity.CENTER）;
tv.setTextSize（20）; 等的EditText =新的EditText（本）;
。etStr = et.getText（）的toString（）; alertDialogBuilder.setView（等）;
alertDialogBuilder.setTitle（职称）;
alertDialogBuilder.setMessage（输入学号）;
alertDialogBuilder.setCustomTitle（电视）; 如果（ISERROR）
alertDialogBuilder.setIcon（R.drawable.icon_warning）;
// alertDialogBuilder.setMessage（消息）;
alertDialogBuilder.setCancelable（假）; //设置负取消按钮
alertDialogBuilder.setNegativeButton（取消，新DialogInterface.OnClickListener（）{
公共无效的onClick（DialogInterface对话，诠释whichButton）{
dialog.cancel（）;
}
}）; //设置正是按钮
alertDialogBuilder.setPositiveButton（OK，
新DialogInterface.OnClickListener（）{
公共无效的onClick（DialogInterface对话，诠释它）{
如果（ISERROR）
完（）;
其他{
意向意图=新意图（
ChangeDeviceActivity.this，
MyPageActivity.class）;
startActivity（意向）;
}
}
}）; AlertDialog alertDialog = alertDialogBuilder.create（）; 尝试{
alertDialog.show（）;
}赶上（例外五）{
//窗口管理$ BadTokenException将被捕获和应用程序会
//不显示'强制关闭的消息
e.printStackTrace（）;
}
目前，这仅仅是一个的EditText 与 alertDialogBuilder.setMessage（输入学号）成立的消息; ，但我想使这个的TextView 这样我就可以居中证明它。我该怎么做呢？
解决方案
AlertDialog.Builder alertDialogBuilder =新AlertDialog.Builder（本）; 的LinearLayout布局=新的LinearLayout（本）;
LinearLayout.LayoutParams PARMS =新LinearLayout.LayoutParams（LinearLayout.LayoutParams.MATCH_PARENT，LinearLayout.LayoutParams.WRAP_CONTENT）;
layout.setOrientation（LinearLayout.VERTICAL）;
layout.setLayoutParams（PARMS）; layout.setGravity（Gravity.CLIP_VERTICAL）;
layout.setPadding（2，2，2，2）; TextView的电视=新的TextView（本）;
tv.setText（职称）;
tv.setPadding（40，40，40，40）;
tv.setGravity（Gravity.CENTER）;
tv.setTextSize（20）; 等的EditText =新的EditText（本）;
。etStr = et.getText（）的toString（）;
TextView的TV1 =新的TextView（本）;
tv1.setText（输入学号）; LinearLayout.LayoutParams tv1Params =新LinearLayout.LayoutParams（LinearLayout.LayoutParams.MATCH_PARENT，LinearLayout.LayoutParams.WRAP_CONTENT）;
tv1Params.bottomMargin = 5;
layout.addView（TV1，tv1Params）;
layout.addView（ET，新LinearLayout.LayoutParams（LinearLayout.LayoutParams.MATCH_PARENT，LinearLayout.LayoutParams.WRAP_CONTENT））; alertDialogBuilder.setView（布局）;
alertDialogBuilder.setTitle（职称）;
// alertDialogBuilder.setMessage（输入学号）;
alertDialogBuilder.setCustomTitle（电视）; 如果（ISERROR）
alertDialogBuilder.setIcon（R.drawable.icon_warning）;
// alertDialogBuilder.setMessage（消息）;
alertDialogBuilder.setCancelable（假）; //设置负取消按钮
alertDialogBuilder.setNegativeButton（取消，新DialogInterface.OnClickListener（）{
公共无效的onClick（DialogInterface对话，诠释whichButton）{
dialog.cancel（）;
}
}）; //设置正是按钮
alertDialogBuilder.setPositiveButton（OK，新DialogInterface.OnClickListener（）{
公共无效的onClick（DialogInterface对话，诠释它）{
如果（ISERROR）
完（）;
其他{
意向意图=新意图（ChangeDeviceActivity.this，
MyPageActivity.class）; startActivity（意向）;
}
}
}）; AlertDialog alertDialog = alertDialogBuilder.create（）; 尝试{
alertDialog.show（）;
}赶上（例外五）{
//窗口管理$ BadTokenException将被捕获和应用程序会
//不显示'强制关闭的消息
e.printStackTrace（）;
}
I've been trying to add two elements in a default AlertDialog but I can't seem to make it work. Here's my code:
// START Dialog
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
TextView tv = new TextView(this);
tv.setText(title);
tv.setPadding(40, 40, 40, 40);
tv.setGravity(Gravity.CENTER);
tv.setTextSize(20);
EditText et = new EditText(this);
etStr = et.getText().toString();
alertDialogBuilder.setView(et);
alertDialogBuilder.setTitle(title);
alertDialogBuilder.setMessage("Input Student ID");
alertDialogBuilder.setCustomTitle(tv);
if (isError)
alertDialogBuilder.setIcon(R.drawable.icon_warning);
// alertDialogBuilder.setMessage(message);
alertDialogBuilder.setCancelable(false);
// Setting Negative "Cancel" Button
alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
// Setting Positive "Yes" Button
alertDialogBuilder.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
if (isError)
finish();
else {
Intent intent = new Intent(
ChangeDeviceActivity.this,
MyPageActivity.class);
startActivity(intent);
}
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
try {
alertDialog.show();
} catch (Exception e) {
// WindowManager$BadTokenException will be caught and the app would
// not display the 'Force Close' message
e.printStackTrace();
}
For now, this is only an EditText with a message set by alertDialogBuilder.setMessage("Input Student ID"); but I want to make this a TextView so I can center-justify it. How do I do this?
解决方案
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
LinearLayout layout = new LinearLayout(this);
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(parms);
layout.setGravity(Gravity.CLIP_VERTICAL);
layout.setPadding(2, 2, 2, 2);
TextView tv = new TextView(this);
tv.setText(title);
tv.setPadding(40, 40, 40, 40);
tv.setGravity(Gravity.CENTER);
tv.setTextSize(20);
EditText et = new EditText(this);
etStr = et.getText().toString();
TextView tv1 = new TextView(this);
tv1.setText("Input Student ID");
LinearLayout.LayoutParams tv1Params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
tv1Params.bottomMargin = 5;
layout.addView(tv1,tv1Params);
layout.addView(et, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
alertDialogBuilder.setView(layout);
alertDialogBuilder.setTitle(title);
// alertDialogBuilder.setMessage("Input Student ID");
alertDialogBuilder.setCustomTitle(tv);
if (isError)
alertDialogBuilder.setIcon(R.drawable.icon_warning);
// alertDialogBuilder.setMessage(message);
alertDialogBuilder.setCancelable(false);
// Setting Negative "Cancel" Button
alertDialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.cancel();
}
});
// Setting Positive "Yes" Button
alertDialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
if (isError)
finish();
else {
Intent intent = new Intent( ChangeDeviceActivity.this,
MyPageActivity.class); startActivity(intent);
}
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
try {
alertDialog.show();
} catch (Exception e) {
// WindowManager$BadTokenException will be caught and the app would
// not display the 'Force Close' message
e.printStackTrace();
}
