Java Android应用程序停止拨打电话

Java Android应用程序停止拨打电话,java,android,android-activity,Java,Android,Android Activity,这里是主要活动 import android.content.Intent; import android.net.Uri; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Te

这里是主要活动

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity {

EditText number;
Button makecall;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    number = findViewById(R.id.number);
    makecall = findViewById(R.id.makecall);

}

private void call() {
    makecall.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent;
            intent = new Intent(Intent.ACTION_DIAL);
            intent = intent.setData(Uri.parse("number:"+number.getText().toString()));
            startActivity(intent);
        }
    });
}
}
我已将此权限请求添加到清单文件

<uses-permission android:name="android.permission.CALL_PHONE"/>

这是我的XML文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"

<EditText
    android:id="@+id/number"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Number"
    android:inputType="number"
    android:maxLength="11" />

<Button
    android:id="@+id/makecall"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Make a call" />
</LinearLayout>

当我按下呼叫按钮打电话时,我发现这个错误

致命异常:主

流程:com.example.bimstajyer1.calisma10,PID:25198 android.content.ActivityNotFoundException:未找到要处理的活动 Intent{act=android.Intent.action.DIAL dat=number:}

错误行为:startActivity(intent)

请调查一下

private void call() {
makecall.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent;
        intent = new Intent(Intent.ACTION_DIAL);
        intent.setData(Uri.parse("tel:"+number.getText().toString()));
        startActivity(intent);
    }
});
}
})); }

现在跳过所有崩溃

你为什么打电话;方法,在onCreate()中设置click listener in按钮,验证您的号码,然后调用call()方法。
private void call() {
makecall.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
            PackageManager pm = getPackageManager();
            if (pm.hasSystemFeature(PackageManager.FEATURE_TELEPHONY)) {
               if (!number.contains("tel:"))
                    number = "tel:" + number;
                Uri link = Uri.parse(number);
                Intent callIntent = new Intent(Intent.ACTION_DIAL, link);
                startActivity(callIntent);
            }else{
                Toast.makeText(this,"No call facility available in device!",Toast.LENGTH_SHORT).show();
