在视图下方显示烤面包部件 [英] Show toast widget underneath a view
本文介绍了在视图下方显示烤面包部件的处理方法，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
查看布局在这里。
通常，烤面包视图出现在屏幕的底部中心。 OnClick被调用后，我想让它出现在下面（8dp）Submit按钮。如何实现这一点。
请参阅我的更新完成项目在这里。
package com.lookjohn.guessnumber;
import java.util.Random;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity {
随机随机;
按钮按钮;
EditText文字;
int input;
int MIN，MAX;
int comp;
int guesses;
public void onCreate（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）;
setContentView（R.layout.activity_main）;
random = new Random（）;
button =（Button）findViewById（R.id.button1）;
text =（EditText）findViewById（R.id.editText1）;
MIN = 1;
MAX = 100;
comp = random.nextInt（MAX - MIN + 1）+ MIN; //生成1到100之间的随机数。
guesses = 0;
button.setOnClickListener（myhandler1）;
}
View.OnClickListener myhandler1 = new View.OnClickListener（）{
public void onClick（View v）{
/ /实现最大数量的猜测，检测
//数量的猜测并从方法返回。
String value = text.getText（）。toString（）; //从editTextView的输入获取值
//如果用户提交一个空的EditText，返回以防止崩溃。
if（value.isEmpty（））{
Toast.makeText（MainActivity.this，你必须输入一个猜测！，Toast.LENGTH_SHORT）;
return;
}
input = Integer.parseInt（value）; //将字符串转换为整数
guesses ++;
if（input> 100）{
Toast.makeText（MainActivity.this，
该数字大于100. Not valid！，
Toast.LENGTH_SHORT）。显示（）;
return;
}
else if（input< comp）
Toast.makeText（MainActivity.this，
你的数字太小了，
Toast.LENGTH_SHORT）.show（）;
else if（input> comp）
Toast.makeText（MainActivity.this，
你的数字太大了，
Toast.LENGTH_SHORT）.show（）;
else
Toast.makeText（MainActivity.this，
好工作！答案是+ comp +.\\\
+
你做了+猜猜+ guesses.\\\
+
重新启动应用再试一次。，
Toast.LENGTH_LONG）.show（）;
}
};
@Override
public boolean onCreateOptionsMenu（菜单菜单）{
//扩充菜单;如果存在，则会将项目添加到操作栏。
getMenuInflater（）。inflate（R.menu.main，menu）;
返回true;
}
}
解决方案
从我学到的知识来看，这是我想到的最好的方案。如果（输入> 100）{
Toast（$）
toast = Toast.makeText（MainActivity.this，
R.string.over_guess，
Toast.LENGTH_SHORT）;
toast.setGravity（Gravity.CENTER，0，0）;
toast.show（）;
return;
}
else if（input< comp）{
Toast toast = Toast.makeText（MainActivity.this，
getString（R.string.guess_low，input），
Toast.LENGTH_SHORT）;
toast.setGravity（Gravity.CENTER，0，0）;
toast.show（）;
}
else if（input> comp）{
Toast toast = Toast.makeText（MainActivity.this，
getString（R.string.guess_high，input），
Toast.LENGTH_SHORT）;
toast.setGravity（Gravity.CENTER，0，0）;
toast.show（）;
}
else {
Toast toast = Toast.makeText（MainActivity.this，
getString（R.string.correct，comp，guesses），
Toast.LENGTH_LONG ）;
toast.setGravity（Gravity.CENTER，0，0）;
toast.show（）;
}
For those who helped me out earlier regarding this project, thank you very much! My code no longer has any problems, and I made extra tweaks. Now that the app is actually robust now, I want to do one more thing.
See screenshot of the layout here.
Normally, the toast view appears at the bottom center of the screen. I want to make it appear just below (8dp) the Submit button once OnClick is called. How can I accomplish this.
See my updated complete project here.
package com.lookjohn.guessnumber;
import java.util.Random;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity {
Random random;
Button button;
EditText text;
int input;
int MIN, MAX;
int comp;
int guesses;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
random = new Random();
button = (Button)findViewById(R.id.button1);
text = (EditText)findViewById(R.id.editText1);
MIN = 1;
MAX = 100;
comp = random.nextInt(MAX - MIN + 1) + MIN; // Generate random number between 1 and 100.
guesses = 0;
button.setOnClickListener(myhandler1);
}
View.OnClickListener myhandler1 = new View.OnClickListener() {
public void onClick(View v) {
// Implemented max number of guesses, detect
// number of guesses and return from the method.
String value = text.getText().toString(); // Get value from input from editTextView
// If user submits an empty EditText, return to prevent a crash.
if (value.isEmpty()) {
Toast.makeText(MainActivity.this, "You must enter a guess!", Toast.LENGTH_SHORT);
return;
}
input = Integer.parseInt(value); // Turn string into integer
guesses++;
if (input > 100) {
Toast.makeText(MainActivity.this,
"That number is greater than 100. Not Valid!",
Toast.LENGTH_SHORT).show();
return;
}
else if (input < comp)
Toast.makeText(MainActivity.this,
"Your number is too small.",
Toast.LENGTH_SHORT).show();
else if (input > comp)
Toast.makeText(MainActivity.this,
"Your number is too big.",
Toast.LENGTH_SHORT).show();
else
Toast.makeText(MainActivity.this,
"Good job! The answer was " + comp + ".\n" +
"You made " + guesses + " guesses.\n" +
"Restart the app to try again.",
Toast.LENGTH_LONG).show();
}
};
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
解决方案
From what I learned, this is the best I came up with for the program. Doing this puts the Toast message in the center of the phone.
if(input > 100) {
Toast toast = Toast.makeText(MainActivity.this,
R.string.over_guess,
Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
return;
}
else if(input < comp) {
Toast toast = Toast.makeText(MainActivity.this,
getString(R.string.guess_low, input),
Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
else if(input > comp) {
Toast toast = Toast.makeText(MainActivity.this,
getString(R.string.guess_high, input),
Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
else {
Toast toast = Toast.makeText(MainActivity.this,
getString(R.string.correct, comp, guesses),
Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
