如何在點擊按鈕後將textview1的值放入textview2？

Question

我希望textview1（用戶要求）的值在點擊按鈕後進入textview2。 你能幫我嗎？

Answer 1

TextView textView1 = (TextView) findViewById(R.id.yourTextView1); 
    TextView textView2 = (TextView) findViewById(R.id.yourTextView2); 
    Button button = (Button) findViewById(R.id.yourButton); 
button.setOnClickListener(new View.OnClickListener(){ 
     textView2.setText(textView1.getText()); 
    }); 

Answer 2

試試這個

final TextView textView1 = (TextView)findViewById(R.id.a); 
     final TextView textView2 = (TextView)findViewById(R.id.b); 
     Button button = (Button)findViewById(R.id.c); 

     button.setOnClickListener(new View.OnClickListener(){ 
      textView2.setText(textView1.getText()); 
     }); 

Answer 3

public void onClick(View view) {  
    if(view == clickBtn) { 
     text2.setText(text1.getText().toString()); 
    }  
}
