单击按钮后，如何将textview1的值输入textview2？

Question

我希望textview1（由用户询问）的值在点击按钮后进入textview2。 你可以帮帮我吗？

Answer 1

试试这个

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 2

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 3

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