我想創建一個數字小鍵盤，但是當我點擊任何一個textview時，它不會在EditText中顯示任何數字。我認爲TextView的OnClickListener事件不起作用。我怎樣才能解決這個問題？無法創建自定義數字小鍵盤
這是我的代碼。
MainActivity.java
public class MainActivity extends Activity {
EditText edtpassword;
TextView tv1;
TextView tv2;
TextView tv3;
TextView tv4;
TextView tv5;
TextView tv6;
TextView tv7;
TextView tv8;
TextView tv9;
TextView tv10;
ImageView iv11;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_keypad);
edtpassword = (EditText)findViewById(R.id.edtpassword);
tv1=(TextView)findViewById(R.id.anti_theft_t9_key_1);
tv2=(TextView)findViewById(R.id.anti_theft_t9_key_2);
tv3=(TextView)findViewById(R.id.anti_theft_t9_key_3);
tv4=(TextView)findViewById(R.id.anti_theft_t9_key_4);
tv5=(TextView)findViewById(R.id.anti_theft_t9_key_5);
tv6=(TextView)findViewById(R.id.anti_theft_t9_key_6);
tv7=(TextView)findViewById(R.id.anti_theft_t9_key_7);
tv8=(TextView)findViewById(R.id.anti_theft_t9_key_8);
tv9=(TextView)findViewById(R.id.anti_theft_t9_key_9);
tv10=(TextView)findViewById(R.id.anti_theft_t9_key_clear);
iv11=(ImageView)findViewById(R.id.anti_theft_t9_key_backspace);
setViews();
}
private void setViews(){
tv1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
onT9KeyClicked(1);
}
});
tv2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
onT9KeyClicked(2);
}
});
tv3.setOnClickListener(new OnClickListener() {
@Override

}
});
tv4.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub

}
});
tv5.setOnClickListener(new OnClickListener() {
@Override

}
});
tv9.setOnClickListener(new OnClickListener() {
@Override

onT9KeyClicked(9);
}
});
tv10.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
onT9KeyClicked(10);
}
});
// find view references...
// set OnClickListener to each key view...
}
private void onT9KeyClicked(int key) {
switch (key) {
case R.id.anti_theft_t9_key_0:
edtpassword.setText(1);
// edtpassword.append("0");
break;
case R.id.anti_theft_t9_key_1:
edtpassword.append("1");
break;

edtpassword.append("8");
break;
case R.id.anti_theft_t9_key_9:
edtpassword.append("9");
break;
case R.id.anti_theft_t9_key_backspace: {
// delete one character
String passwordStr = edtpassword.getText().toString();
if (passwordStr.length() > 0) {
String newPasswordStr = new StringBuilder(passwordStr)
.deleteCharAt(passwordStr.length() - 1).toString();
edtpassword.setText(newPasswordStr);
}
}
break;
case R.id.anti_theft_t9_key_clear:
// clear password field
edtpassword.setText(null);
break;
}
}
}
這是我的佈局文件。

改變了代碼，但仍然當我按任何數字它不顯示在密碼的textview上。 :( – user3354610 2014-12-13 09:10:19
