按钮的 onClick() 没有被调用

Question

我正在尝试创建一个呼叫按钮，当用户点击一个按钮时，它会进行 phone 呼叫。

现在我有了单选按钮和该按钮的代码，但是单击它时什么也没做。

我已经在清单中设置了 CALL_PHONE 和 READ_PHONE_STATE 权限，但按下按钮后仍然无法正常工作。

这是 activity 中单选按钮的代码：

Button radioButton;
call();


radioButton = (Button) findViewById(R.id.radioButton);
}

private void call()
{
    Intent in = new Intent(Intent.ACTION_DIAL,Uri.parse("0000000000"));
    try{
        startActivity(in);
    }
    catch (android.content.ActivityNotFoundException ex)
    {
        Toast.makeText(getApplicationContext(),"yourActivity is not founded",Toast.LENGTH_SHORT).show();
    }
}

创建 RadioGroup，然后在 RadioGraoup

中创建 RadioButton

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() 
{
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        RadioButton callRadioButton=(RadioButton)findViewById(checkedId);

        //gettext you write with radiobutton
        String  dailString=callRadioButton.getText().toString();

        //check if you select the radio button
        if(dailString.trim().equals("dailnumber"){
            Intent intent = new Intent(Intent.ACTION_DIAL);
            intent.setData(Uri.parse("tel:0123456789")); 
            startActivity(intent); 
        }else{ 
        // do action with other android button
        }
    } 
});

  }}

Answer 2

首先，您没有在单击单选按钮时调用 Call 方法。这是您的问题的解决方法。

第一种方式：

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
    radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() 
    {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
               call();
} });

然后像这样调用你的方法

private void call(){
    Intent in = new Intent(Intent.ACTION_DIAL,Uri.parse("0000000000"));
    try{
        startActivity(in);
    }
    catch (android.content.ActivityNotFoundException ex)
    {
        Toast.makeText(getApplicationContext(),"yourActivity is not founded",Toast.LENGTH_SHORT).show();
    }
}

第二种方式：

Button myButton=(Button)findViewById(R.id.buttonId);

myButton.setOnClickListener(new View.OnClickListener()
{
    @Override
    public void onClick(View v){
       call();     
    }
});
