活性1

button1.setOnClickListener(new View.OnClickListener() {
    @Override  
    public void onClick(View v) {
        Intent intent = new Intent(Activity1.this, Activity2.class);  
        Bundle bundle = new Bundle();
        bundle.putString("p",textview);
        intent.putExtras(bundle);
        startActivity(intent);
    }  
});

活性2

Bundle bundle = this.getIntent().getExtras();
EditText.setText(bundle.getString("p"));

Answer 1

更改

bundle.putString("p",textview);

到

bundle.putString("p",textview.getText());

和

EditText.setText(bundle.getString("p"));

到

EditText editText = (EditText) findViewById(R.id.yourEditText)
editText.setText(bundle.getString("p"));

Answer 2

您需要传递文本，而不是视图本身：

Intent intent = new Intent(Activity1.this, Activity2.class);  
intent.putExtra("p", textview.getText());
startActivity(intent);

Answer 3

实施Activity1之类的

Intent intent = new Intent(Activity1.this, Activity2.class);  
intent.putExtra("p", textview.getText());
startActivity(intent);

实施Activity2之类的

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.balance);
          Editext dt=(EditText)findViewByid(R.id.edittext);
          Bundle bundle = this.getIntent().getExtras();
         dt.setText(bundle.getString("p"));
      }

Intent intent = new Intent(Activity1.this, Activity2.class);  
intent .putString("p",textview.getText().toString());
startActivity(intent);

在活动2

EditText editText = (EditText) findViewById(R.id.yourEditTextId);
