效果:
package com.example.test;
import android.app.Activity;
import android.os.Bundle;
import android.text.method.HideReturnsTransformationMethod;
import android.text.method.PasswordTransformationMethod;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.TextView;
public class MainActivity extends Activity {
private TextView editText1;
private CheckBox checkBox1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
editText1 =(TextView) findViewById(R.id.editText1);
checkBox1=(CheckBox) findViewById(R.id.checkBox1);
checkBox1.setonCheckedChangeListener(new onCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(isChecked){
//如果选中,显示密码
editText1.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
}else{
//否则隐藏密码
editText1.setTransformationMethod(PasswordTransformationMethod.getInstance());
}
}
});
}
}
关键是:
editText1.setTransformationMethod(HideReturnsTransformationMethod.getInstance()); editText1.setTransformationMethod(PasswordTransformationMethod.getInstance());
