Android的如何使文本显示 [英] Android-How To Make the Text display

问题描述

我是新来android.I有一些code..I有

I am new To android.I have Some Code..I have

Simple.java：

Simple.java :

 public class Simple extends Activity {
     /** Called when the activity is first created. */
      Button show;
      TextView view;
    EditText edit;

 @Override
  public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
       show=(Button)findViewById(R.id.show);
      view=(TextView)findViewById(R.id.view);
      edit=(EditText)findViewById(R.id.edit);


show.setOnClickListener(new OnClickListener(){
    public void onClick(View view){

    show();

    }
});

}

public void show(){
    String text=edit.getText().toString();
    view.setText(text);
    Intent t=new Intent(this,Show.class);
    startActivity(t);

}

}

当我试图以显示它的工作原理相同的活动的文字...
我想通过我输入了的EditText，并把它显示给Show.class文本

When i tried To Display the text in the same activity it works... I am trying to pass the text Which i typed in EditText and to display it to Show.class

在code为Show.class

the code for Show.class

公共类展会扩展活动{

private Simple simple;
TextView text1;
Button back;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.next);
    back=(Button)findViewById(R.id.button);
    text1=(TextView)findViewById(R.id.then);

    back.setOnClickListener(new OnClickListener(){
        public void onClick(View view){
            start();
        }
    });
}
public void start(){
        String t=simple.edit.getText().toString();
        text1.setText(t);

    Intent t=new Intent(this,Simple.class);
    startActivity(t);
}

}

我想这一次我不能够显示这是我给的EDITTEXT在Simple.java的文本。
我知道这是基本的，但我知道。所以，请帮我out.Thanks提前..

I tried this one I am not able to Display the text which i gave in editText in Simple.java. I know it is basic but I do know. So Please Help me out.Thanks in Advance..

推荐答案

尝试添加这表明（）：

Intent t = new Intent(this, Simple.class);
t.putExtra("editText", text);
startActivity(t);

然后在您的显示类的start（）方法，使用：

Then in your Show class' start() method, use:

Intent t = getIntent();
Bundle data = t.getExtras();
text1.setText(data.getString("editText"));

我没有测试过这一点（您实现......我稍微混淆），但putExtra和getExtra功能是什么，你可能会希望使用。

I have not tested this (and am slightly confused by your implementation...) but the putExtra and getExtra functions are what you will likely wish to use.
